Initial analysis

The Martin 2007 Trust-owned duplex at 291 Union Street in Telegraph Hill is a three-story multi-family residential building constructed in 1900. The property has a documented history of maintenance focused primarily on roofing and deck-related improvements. Most recently, in May 2022, a reroofing project was filed, following a consistent pattern of roofing work that has occurred approximately every three years dating back to 1990 when the first re-roofing permit was issued. The building has also undergone significant deck maintenance, with completed work in 1993 involving the replacement of a portion of the second-floor rear deck, and an earlier repair to rotted railings and waterproof deck surface in 1995, though this permit has since expired and its work status is unclear. Additional historical maintenance records from 1987 indicate replacement of rotted materials, suggesting ongoing structural upkeep. More recently, an informational planning record was closed regarding height limits and lot average considerations for a potential horizontal addition in the rear yard, though this appears to be regulatory in nature with no immediate impact on the building's current status.

Risk rating

How 291 Union St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
76th percentile

Out of 684 buildings in this neighborhood, 164 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 87.1%
Moderate concern 8.0%
Severe concern 4.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
